A new species of dinosaur recently discovered in the Hell Creek Formation in Montana has been described as the youngest known dromaeosaurid and was a close cousin of the Velociraptor.
Scientists have discovered a new species of a small horse that lived 4.4 million years ago in Ethiopia. The ancient horse was among a diverse array of animals that lived in the same areas as the ancient human ancestor Ardipithecus ramidus, or Ardi.
A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists
A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists have discovered.
At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history.
The discovery of a lone tooth in the Riversleigh World Heritage Area of Queensland, Australia has led to the classification of a new, giant, now-extinct species of platypus known as the Obdurodon tharalkooschild.
The integration of Pangea that began during the early Permian period may have caused the environment to deteriorate, playing a role in the mass extinction event that occurred 250 million years ago.
While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum, researchers have found a second instance of mammalian “dwarfing” attributable to increasing temperatures.
An analysis of a 1.8 million-year-old human skull suggests that the earliest members of our Homo genus actually belonged to a single species, a finding that contradicts previous beliefs that there were several different human species walking the Earth during that time.
Despite the general perception that recycling is a fairly modern phenomenon, there is growing evidence it dates back to the days of the early hominids, researchers said this week during a four-day conference at Tel Aviv University in Israel.
Mapinguari The mapinguari or mapinguary is an ape-like cryptid said to inhabit the Amazon rainforests of Brazil and Bolivia. It is also known as the Isnashi. Several attempts to find physical evidence that the creature exists have been conducted. Samples have been gathered, but when analyzed it was found to be from known animals and some of the castings of tracks were inconclusive. Native folklore has described the creature as having only one eye, long claws, backward feet, a...
Palaeovespa is a genus of wasps that holds seven species, all of which are extinct. Two of the species were discovered in Baltic amber deposits from Europe dating back to the middle Eocene era, while the other five were found in Florissant Formation amber from the Priabonian stage era in Colorado in the United States. This genus, and four of its species, was first described in 1906 by Dr. Theodore Cockerell in the Bulletin of the Museum of Comparative Zoology. Cockerell described all but one...
Australopithecus africanus was an early hominid, an australopithecine that lived between roughly 3.03 and 2.04 million years ago in the later Pliocene and early Pleistocene. Au. africanus was of slender build and was thought to have been a direct ancestor of modern humans. Fossil remains signify that Au. africanus was considerably more like modern humans that Au. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. This hominid has only been...
Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...
Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
